DM38X double stream, 5MP resolution jpegencoder and hdmi interface

Hu Yan

Other Parts Discussed in Thread: DM388

Dear all:

we are using IPNC_RDK_3.8， hardware DM388 and imx172 sensor, to capture image of 5mp resolution, display in lcd, and save jpg file.

so the link may be cameralink->out[0] 5mp -------->dupLink---->encLink;

cameralink->out[1] 1080p-------> dupLink -->display[];

I changed code at Multich_capturedisplay.c,but failed.

could you give me some advice?.

thanks.

Hi,

Can you provide more details on the issue? Is simple capture -> HDMI display working?

Hi,

In the IPNC RDK we have the snapshot feature which will save the latest JPEG frame to a file.

Pl. study the following files under the keyword 'snapEnable':

..\ipnc_rdk\ipnc_mcfw\demos\mcfw_api_demos\stream\stream.c
..\ipnc_rdk\ipnc_mcfw\demos\mcfw_api_demos\multich_usecase\ti_mcfw_ipcbits.c

The snapshot will work only if the use case is generating a JPEG stream.

regards,

Anand
